Wrapping Up…

As it is in any competitive field in the cybersecurity game the bad guys constantly try to outrun the good guys and the other way around.

Some food for thought – at the end of the day no single tool is bulletproof. One should not relax and rely on one software alone or on a single app to keep you safe as they all have their flaws, all have their vulnerabilities.

It is not a bad idea to try to think and act like a journalist – question and be suspicious about everything you receive or run into the digital world and looks slightly suspicious.

Check once, check twice check thrice may you need to do so before you act or click on it; be sure you are not engaging anything that looks fishy.

Stay on the safe side of digital life!
